Found the issue, thanks for the example, it helped! Try the latest version.
Thx for the fix :) I can import my models directly from blockbench to construct now. There's just another problem, with the blender modification, I had my models textures pixel perfect (as I'm going with a pixel art 3D style, I can't have my textures blurry) Is there something you could do about that please ? Thx again ! EDIT : I fixed it, it's related to the project Sampling setting, I just put it to Nearest and texture is now pixel perfect.
